We extend thresholding methods for numerical realization of mean curvature\nflow on obstacles to the anisotropic setting where interfacial energy depends\non the orientation of the interface. This type of schemes treats the interface\nimplicitly, which supports natural implementation of topology changes, such as\nmerging and splitting, and makes the approach attractive for applications in\nmaterial science. The main tool in the new scheme are convolution kernels\ndeveloped in previous studies, that approximate the given anisotropy in a\nnonlocal way. We provide a detailed report on the numerical properties of the\nproposed algorithm.\n
